5-Ferrocenylpyrimidine (FcPM) reacts with dinuclear copper(II) carboxylates ([Cu-2(RCOO)(4)]; R = C6H5, C5H11, CH3) to produce one-dimensional coordination polymers [Cu-2(C6H5COO)(4)(FcPM)](n) (1), [Cu-2(C5H11COO)(4)(FcPM)](n) center dot nCH(3)CN (2), and a discrete tetranuclear complex [Cu-2(CH3COO)(4)(FcPM)(2)] (3). Compounds I and 2 show similar zigzag chain structures, comprising alternate linking of FcPM and dinuclear copper(II) units, whereas the structure of 3 corresponds to the local structural motifs of 1 and 2. Reaction of FcPM with zinc salts (ZnX2; X = NO3, SCN) affords zinc-centered ferrocenyl cluster complexes, [Zn(NO3)(2)(FcPM)(3)] (4) and [Zn(SCN)(2)(FcPM)(2)] center dot 0.5H(2)O (5), with varying M:L ratios. FcPM acts as a bidentate ligand in 1 and 2, and as a monodentate ligand in the others. (c) 2005 Elsevier B.V. All rights reserved.
